A Distributed Multi-Authority Attribute Based Encryption Scheme for Secure Sharing of Personal Health Records
2017
Personal health records (PHR) are an emerging health information exchange model, which facilitates PHR owners to efficiently manage their health data. Typically, PHRs are outsourced and stored in third-party cloud platforms. Although, outsourcing private health data to third-party platforms is an appealing solution for PHR owners, it may lead to significant privacy concerns, because there is a higher risk of leaking private data to unauthorized parties. As a way of ensuring PHR owners' control of their outsourced PHR data, attribute based encryption (ABE) mechanisms have been considered due to the fact that such schemes facilitate a mechanism of sharing encrypted data among a set of intende…
Advance Directives. Comparison of current legislation within the European Union
2021
Abstract Advance Directives have been legally binding in Spain since the publication of Act 41/2002, of 14th November, which regulates patients’ rights to autonomy and obligations concerning clinical information and recording clinical information. However, the situation in each country of the European Union remains heterogeneous and unknown to most health care professionals. By collecting and studying the legislation on patients' rights in European Union countries we have made an updated comparison of the different features of Advance Directives in each country. Only 15 of the 28 European Union Countries have developed specific rules on advance directives which makes them legally binding in…
Attribute based access control scheme with controlled access delegation for collaborative E-health environments
2017
Abstract Modern electronic healthcare (e-health) settings constitute collaborative environments with complex access requirements. Thus, there is a need for sophisticated fine-grained access control mechanisms to cater these access demands and thereby experience the full potential of e-health systems. In order to realize a flexible access control scheme, integrating access delegation is of paramount importance. However, access delegation has to be enforced in a controlled manner so that it will not jeopardize the security of the system. In this paper, we addressed this issue through proposing an attribute based access control scheme integrated with controlled access delegation capabilities. …
Blockchain Based Delegatable Access Control Scheme for a Collaborative E-Health Environment
2018
Modern electronic healthcare (e-health) settings constitute collaborative environments requiring sophisticated fine-grained access control mechanisms to cater their access demands. Access delegatability is quite crucial to realize fine-grained, flexible access control schemes compatible with such environments. In this paper, we addressed this issue through proposing an attribute based access control scheme integrated with controlled access delegation capabilities suitable for a multi-domain e-health environment. We have utilized the blockchain technology to manage attribute assignments, delegations as well as revocations. The scheme enables delegations in a controlled manner without jeopard…
La revoca dello stato di liquidazione: interessi in gioco e questioni ancora aperte
2017
L'articolo analizza in dettaglio la disciplina della revoca dello stato di liquidazione di cui all'art. 2487-terc.c. Sebbene l'introduzione di tale norma nel 2003 abbia avuto il merito di sancire in modo chiaro e definitivo la revocabilità dello stato di liquidazione delle società di capitali, molti altri aspetti restano ancora in ombra. Fra questi ultimi, assumono particolare rilievo: (i) la possibilità di revocare lo stato di liquidazione nelle società di persone; (ii) l'ambito di applicazione temporale della disciplina in esame; (iii) le interconnessioni tra il recesso dei soci dissenzienti e lo scioglimento della società; (iv) le modalità di preventiva eliminazione di talune cause di sc…
Un'ipotesi sulla revoca della donazione per ingratitudine del liberto
2022
The paper deals with the reasons that led Emperor Philip the Arab to introduce the gift revocation, due to the ingratitude of the Freedman. According to the Author, the reform depended on the desire to remedy the iniquity that could come from the revocatio in servitutem due to the ingratitude of the Freedman, arranged by the reform of Commodus, known through a Modestinus fragment (Mod. lib. sing. de manum. 25.3.6.1). According to the said reform – that could apply in similar cases, as happens in Paul. 11 ad ed. D. 4.2.21 pr. – the ungrateful Freedman was assigned by the judge as a slave to an emptor, who paid the price of the slave to the patronus. The new dominus would also have bought the…
La revoca e la decadenza delle concessioni autostradali
2020
L’art. 35, D.L. 30 dicembre 2019, n. 162, prevede una serie di novità in materia di concessioni autostradali. In particolare, si stabilisce che, in caso di revoca, decadenza o risoluzione delle concessioni autostradali esistenti, l’ANAS subentri ai precedenti concessionari, per il tempo strettamente necessario a espletare le procedure di gara funzionali all’individuazione di un nuovo concessionario. Inoltre, si dispone che, ai fini della determinazione dell’indennizzo, siano da considerarsi nulle le clausole convenzionali difformi rispetto alle norme del codice dei contratti pubblici e che l’efficacia del provvedimento di revoca, risoluzioneo decadenzanonsia sottoposto alla condizione del p…
Subjectivity construction in school failure paths. Transition pathways provided for labour insertion for adolescents at risk
2017
RESUMEN La modernización del sistema de Formación Profesional del Estado español se remonta a los años 90. Desde entonces, ha evolucionado significativamente, teniendo los desarrollos europeos como marco de referencia. Con la extensión de la escolarización hasta los 16 años, se introdujo en el año 1994 un tipo de formación profesionalizadora de muy bajo nivel de cualificación, especialmente diseñada para los adolescentes clasificados como de bajo rendimiento académico en Educación Secundaria y para aquellos en situación de vulnerabilidad social. Esta formación fue rediseñada en 2006 y en 2013. Nuestra contribución, enmarcada en una investigación más amplia desarrollada en el seno de un proy…
